Why is Hanoi hot in winter days?

These days, the North, typically Hanoi, is in a state of early morning cold weather, but in the daytime it is hot as summer, even though it has entered the winter.

Although the North has entered the winter, many people still feel like the summer. Mr. Vu Anh Tuan - Head of Disaster Risk Warning, National Center for Hydro-Meteorological Forecasting - explained: This year's winter starts early with the first monsoon in the early days of September. However, in the beginning of the season, cold air waves when affecting our country occur not frequently, about 7-10 days there is only one wave, unlike the mid-season, maybe 4-5 there is a day again.

At the same time, during the early season, alternating between cold air periods will be warm sun waves; also in the end of the season, there is a drizzling phenomenon and fog alternating between cold air waves. This can be considered a normal phenomenon of weather and climate in the early winter.

"The main cause of the dry sunshine in the early season as in recent days may be due to two reasons: The first is the influence of the low pressure area in the West and the second reason is because the cold air encroached deep down. Male, causing rain to the Central region when combining the terrain of Truong Son range, and the North is located deep in the cold air mass so it is dry " - Mr. Tuan explained.

According to Mr. Tuan, this "half-summer and mid-autumn" weather condition is about to end because in the next few days, the North will welcome a new cold wave.
